System, method, and program product for simulating test equipment

Abstract

A simulation system includes a Response database for storing Response Data in which an output result of a device-under-test (DUT) model for a predetermined test item is set, and a framework for causing the test plan program to operate. The framework determines an output result of a DUT or a DUT model for a predetermined test item, which is executed based on the test plan program, based on the Response Data stored in the Response database. That enables a test flow to be verified in an offline simulation environment of the test equipment without loading a pattern program.
